There are no branches in that break up scene at all. It plays out the exact same way no matter what you've done prior in the game.
Mel says virtually fuck all in episode six. She almost has more lines in the DnG game than she has for the rest of the episode.
So in that break up scene with Chad and Sage, there's definitely a look that Chad and Mel exchange, but all she says is:
Melanie: "I can't..."
And Sarah responds with:
Sarah: "Shh... It's ok. It will be ok."
And they leave the room.
Later she talks to Sage at lunch, and tries to offer some help.
But definitely there's no "Now we can be together" dialogue, it's just not there.
That's some presidential shit right there!
This is a strange conundrum. You're angry that a guy has dumped a girl you like (meaning she'll be available once she's picked up the pieces). Would you rather he stayed with her?
The logic is very clear. If any of the following are true, Quinn keeps walking:
- pathMayaJosy (this means the girls chose to be in a relationship with the MC at the end of episode 4)
- not quinnLikesYou (this is only set false if you're not playing on a PC - weird one)
- not ep4_quinn_lewd (this means the MC never fucked Quinn on the DIK roof in episode 4)
- affinity != "DIK" (this means you did not predominantly chose DIK path critical choices, like whether you fight the Jocks outside the change rooms etc.)
So
any of the above (it doesn't have to be all) are true, and Quinn walks.
Now if you installed the walkthrough, the scene gets modified and the mc will always have sex with Quinn if you choose "Help Her".
Also note, there are no points with Quinn, just flags regarding previous actions.
